As noted by me at OTB, one question going forward for Democrats is whether or not Barack Obama’s voter breakdown by race carries into the next primary states. Here’s some quick-and-dirty math for Florida’s zero-delegates-except-if-Hillary-says-so primary on Tuesday.

Assuming Obama gets 80% of the black vote and 25% of the non-black vote, and 24% of Florida Democratic primary voters are black (assuming no differential turnout, based on Florida’s registration statistics from December 31st), Obama should get around 38% of the Florida vote. That’s well ahead of how Obama has been polling in Florida, so I’m not at all convinced that the extrapolation works well even though Obama’s average has been tracking upwards slightly in the state and one would expect that Florida whites would be less racially conservative than South Carolina whites. I think the safe money is that Clinton will still win the state and its 0 delegates comfortably, but I wouldn’t be overly surprised with a result like 40–35 or so (with both candidates receiving about equal numbers of those 0 delegates at stake, given the Democrats’ high threshold-PR rules).
